Here's a simple way of explaining RBA - when you update your B button with a new item (example: catch a bug),
it takes the value of the bug (according to the game, bug is 29), and writes that value onto a different section of your inventory.
Which section depends on what item you have on c-right. So, if you have a Goron Mask on c-right (Goron Mask is linked to Tunics & Boots),
it will actually write the value of 29 onto your tunics/boots binary slot. 29 in binary is 0001 1101. If you look at the charts below,
you'll see that this will end up giving you the Kokiri Tunic, the Zora Tunic and the Kokiri Boots (although you already had those boots anyway),
and will delete all other tunics/boots you have (because their values are 0 now).

We need to figure how to update the B button with other items of higher values.
The bottles stop at 32 though, and Bug/29 is the highest useful value we can update things with right now.
As you can see RBA is very limited as of right now, and unless somebody comes up with a breakthrough, it will remain that way.
However, still a lot to be done even with just these possibilities though, so here goes.

Having these items on C-right while changing the value of your B bottle will add new bottles to your inventory. Example: You have the Ocarina of Time on
C-right. You catch a Fairy in your B bottle. Now if you check your inventory, your Bombchu slot will be overwritten with a bottled Fairy!

The list starts off "normally" but becomes staggered. This is because some slots (Ocarina slot, Hookshot slot) can hold multiple items.
It's worth noting that even if you replace a slot that is only usable as a certain Link (example: replace Child Trade Items slot with a bottle),
it is still only equippable with the proper Link. The value of the item in that slot is irrelevant.

After Blue Potion, the game has cycled the inventory once. Now it goes through it again, with the AMOUNT you have of each item slot.

** This is how many Magic Beans you've ever bought from the Bean seller in Zora's River. For example, if the value is set to 6,
he will charge you 70 rupees for a bean. Any values higher than 9 cause him to stop selling beans. Video.

Using RBA with these items on C-Right will simply write the value of your
bottled item on B as the new amount of the item on the right column. Example - catch a fairy in your B bottle while a bottled Poe is on C-right and you will have 24 bombchus.

Alright. The equipment is handled differently - several items are stored within the same byte of data, they merely have on/off switches to
determine if you have them or not. This way the game can save space by storing information like which tunics and boots you have in
one 8-digit binary value.

An example: Lets say the value of the Tunics & Boots byte is 0011 0111. What does that mean? Well, if you convert it into decimal,
you get 55. 55 is 1+2+4+16+32. If you look at the chart below, you will see that this means you have all the tunics and boots
except Hover Boots. By using RBA, you can rewrite this value to the value of one of the modifiers above.

If you delete your Kokiri Tunic, then have a Like-Like eat your remaining Tunic, the game puts the Kokiri Tunic back on you,
despite you not having it. In your inventory the empty slot where the Kokiri Tunic would go will be selected, sort of like how
if you skip the Kokiri Sword, become an adult, then go back in time, you will be wielding the Kokiri Sword, despite having never gotten it,
and it not being in your inventory.

Now the swords & shields byte:

* - Giant's Knife and Biggoron Sword share the same value. There must be a different variable in place somewhere else to determine which one it is.
** - "Broken" is the trigger if the Giant's Knife is broken or not.
Using RBA you can actually get the "Broken" trigger to be on without having the third sword.
This causes there to be the image of the broken sword in your inventory, but the cursor moves right past it when you try to select it.

Ok, now for the left-side equipment. This includes capacity upgrades and some hidden stuff like wallet upgrades.
The way the values here work is very unintuitive. Also, some of the items you can put on here are very strange.
There are 4 slots where items can go -- I will refer to them as slots 1 through 4, with
slot 1 being the top one (typically your bullet bag/quiver) going down to the bottom one (silver and gold scale) as slot 4.
If I mark a value as "x" instead of 0 or 1, it means that bit is not used for the slot I am talking about.

Each left-side equipment slot tends to take up three bits. Slots 2 and 4 have all of their three bits in a single byte,
while slots 1 and 3 are a mixture of two separate bytes. Due to this, there will be two additional charts after the regular
charts to show what a mixture of two bytes can do.

* This works in conjunction with your Bullet Bag. See the chart further down to see what you can do with this.

** Just to save you the time, yes this upgrade is impossible -- the only way would be Halfmilk RBA with the Pocket Egg, but that means the value
must be set to 26, and there is no way to do that to this value. I've tried.

*** You can hold up to 255 (if you buy more it wraps around to 0),
but if you have over 128 and try to use one, it changes to 0. Also, the icons become screwed up once you get over 99. This upgrade is impossible to get as of now.
Well, those are the RBA charts for the left-side equipment. The left-side equipment is pretty complicated with the way the values can relate.
There are a few other things you can do by mixing two values that take up the same slot, in order to get something new.
You can mix your child Bullet Bag with Pocket Egg RBA to get other items on that slot. Here's the chart for that.

I believe Black, Green, Blue, and Bronze all have the strength of Gold, though some might have Silver (I haven't tested).
This is pretty simple to do, just update the Pocket Cucco RBA value with any odd number (something that will end in a 1 in binary).
If you never got any strength upgrades, this gives you the Black Gauntlets, but you can get different colors if you have different upgrades.
Here's a video guide to get these on your console legit.

Quest status is simple. Each bit represents something you either have or do not have.

If you ever do Broken Goron Sword RBA your Light Medallion will be permanently deleted, as there's no way to write a value of 32 or higher (yet).

It is worth noting using a Fish (0001 1001) will give you the Forest Medallion, and the Shadow and Spirit Medallions (rainbow bridge cutscene).
This is extremely useful in a speedrun, as you could literally skip all adult dungeons.

I went ahead and confirmed it -- picking up a heart piece adds 16 to the previous value. The last 4 binary digits do nothing.
Kazooie used this to get 23 and a half hearts.
Unless we can update the B button with an item that has the value of 32 or higher, then 23 hearts is the upper limit.

Dungeon items are the dungeon-specific items, such as the Compass or the Map. You can use RBA to delete or create them.
All of the dungeons hold the data for these items the same way.

If you skip the bomb-bag as a child, then win the bomb-bag upgrade from the Bombchu Bowling Alley and become an adult, then go back to Dodongo's
Cavern and get the Bomb Bag. It will put the Bomb Bag (20) on your Bombchu slot for some reason?
Anyway if you put it on C-right you can edit the Water Temple small key amount. Video.
